What Is Duct Leakage?
The U.S. Department of Energy estimates that 20–30 % of the air you pay to heat or cool escapes through holes, gaps, or unsealed joints in the duct system.DOE Energy Saver.
The Utah Connection
In Utah County—where temperature swings can hit triple-digit summers and freezing winters—HVAC usage already accounts for roughly 40 % of a home’s annual electricity. When 30 % of that conditioned air never reaches the vents, you’re effectively wasting 12 % of every power bill. At next year’s 12.89 ¢ rate, that’s about $15 lost every month for a household using 1,000 kWh.
How Aeroseal® & Professional Cleaning Solve the Problem
The latest Aeroseal field guide shows that sealing can cut leakage by up to 90 % and translate into energy-bill reductions approaching 30 % when paired with a clean duct system.
- Aeroseal duct sealing pinpoints and seals leaks from inside the ductwork.
- NADCA-standard source-removal cleaning clears dust that restricts airflow and strains the blower motor.
Additional Paybacks & Perks
Federal tax credit: The Inflation Reduction Act’s §25C credit covers 30 % of qualified air-sealing costs—up to $1,200 per year for homeowners through 2032.IRS guidance.
Comfort & indoor air quality: Sealed, debris-free ducts deliver even temperatures, quieter operation, and reduced infiltration of outdoor pollutants—especially helpful during Utah’s winter inversion season.
